The essence of this game is picking up every possible item in order to recycle it. With those recycled materials, we can craft new items and earn money. But what are the most profitable items to craft?

First of all, we need to know what is the main price of each unit of recycled material. The only way I found, was calculating it from basic crafting items.

• Plastic fragments $5 (Balloon, $10 per 2 plastic fragments)
  
• Glass $2.5 (Soda Bottle, $5, 2 glasses)
  
• Prank $2.5 (Cafe Chair, $5, 2 pranks)
  
• Scrap Cloth $3 (Jacket, $12, 3 scrap cloths)
  
• Rubber $5 (Mouse Pad, $10, 2 rubbers)
  
• Steel fragments $5 (Pan, $10, 2 steel fragments)
  
• Metal fragments $3.5 (Shopping Basket, $7, 2 metal fragments)
  
• Copper Cable $8.25 (Guitar, $24, $7.5 per 2 Planks and 2 copper cables)
  
• Electronic Circuit $9 (Robot, $24, $15 per 3 Plastic fragments and 1 electronic circuit)

Based on the per-unit prices from the previous list, I calculated how much it costs to craft each item at this workbench. This way, it's easier to compare the crafting cost with the selling price at the shop and figure out which items are more profitable to craft.

• Trampoline: Earn $35, Crafting cost $35
  
• Party Light: Earn $18, Cost $17.5
  
• Shelf: Earn $17, Cost $16
  
• Pipe: Earn $18, Cost $20
  
• Guitar: Earn $24, Cost $24
  
• Dumbbell: Earn $29, Cost $30.5
  
• Wet Floor Bucket: Earn $13, Cost $13.5
  
• Table: Earn $22, Cost $23
  
• Glasses: Earn $10, Cost $10
  
• Robot toy: Earn $24, Cost $24
  
• Wheel: Earn $35, Cost 35.5
  
• Drink Bottle: Earn $13, Cost $10
  
• Baby Cot: Earn $18, Cost 17.5
  
• Skateboard: Earn $15, Cost $15
  
• Purse: Earn $20, Cost $22

From this list, we can see that the most profitable item to craft is Drink Bottle, earning $3 per unit, followed by the Shelf, with a $1 profit, and Party Lights or Baby cots, each offering a $0.5 profit. All other products either offer the same profit as crafting simpler items (like balloons, chairs, etc.) or actually result in a loss.

After unlocking the level 2 workbench, I went ahead and worked out how much it costs to craft each item — and how much profit (or loss) you can make from them.

• Ratón: Earn $27, Crafting Cost $22.25, Profit +$4.75
  
• Teclado: Earn $45, Cost $36.25, Profit +$8.75
  
• Mando: Earn $30, Cost $27.25, Profit +$2.75
  
• Joystick: Earn $30, Cost $27.25, Profit +$2.75
  
• Móvil: Earn $37, Cost $31.25, Profit +$5.75
  
• TV: Earn $50, Cost $45, Profit +$5
  
• LCD TV: Earn $60, Cost $48.5, Profit +$11.5
  
• Carcasa: Earn $105, Cost $88, Profit +$17
  
• Monitor: Earn $80, Cost $70, Profit +$10
  
• Portátil: Earn $85, Cost $60, Profit +$25
  
• Full PC: Earn $335, Cost $216.5, Profit +$118.5
  
• Dardos: Earn $25, Cost $25, Profit +$0
  
• Cascos: Earn $43, Cost $36.25, Profit +$6.75
  
• Cactus: Earn $44, Cost $29.75, Profit +$14.25
  
• Flamenco: Earn $102, Cost $110.5, Profit -$8.5
  
• Pink: Earn $75, Cost $71, Profit +$4
  
• Trébol: Earn $40, Cost $38, Profit +$2
  
• Tuberías: Earn $40, Cost $43, Profit -$3

Personally, I only crafted Full PCs at Workbench 2, since they’re by far the most profitable item. The other products from Workbench 2 required materials needed for Full PCs, so it just wasn’t worth crafting anything else. Instead, I kept crafting items from Workbench 1, prioritizing Drinking Bottles, Shelves, Party Lights, and Baby cots in that order.

To craft a Full PC, you’ll need:

• 2 units of Plastic Fragments
  
• 5 units of Steel Fragments
  
• 10 units of Copper Cables
  
• 11 units of Electronic Circuits

I always kept a stock of these materials directly at Workbench 2. However, since Plastic tends to be easier to find in large amounts, I usually stored extra Plastic at Workbench 1 as well, just to keep more crafting options open.

That’s all! I hope you found this guide helpful.
Apologies if I made any mistake in the calculations — I based all of this on my own experience playing, and honestly, it worked out really well for me.
